Due date: You vs Dr.

At our first visit the tech asked me about my last period and/or if I knew my conception date. I knew the date we conceived and I am positive lol. Measurements ended up coming up with an EDD of 2/14 which they confirmed at the following apt by MD. At my last ultrasound the tech said the baby was measuring a bit ahead and I told her that based on my LMP and when I conceived my EDD should be 2/4 and she suggested I talk to MD because I was accurately measuring for 2/4 due date. I did and MD refused to change it. She said the most accurate dating measurements are taken between 6-9 weeks and after that the baby will gain faster and slower but it wouldn't change due date. It's a bit agitating and know it's not a big deal-- I just wonder why she isn't listening to me. Thanks for the vent ladies.
